Beginning in 2015, the Tokyo Metropolitan Government organizes an industry-government-academia collaboration event, TOKYO Mimi College (called "TOKYO Sign Language College" in 2015), with the aim of deepening understanding and interest in hearing impairment.
Since its start, NEC has co-hosted this event with Tokyo Metropolitan University.

Collaboration with the Tokyo Para-Sports Association began in 2016.

In 2019, NEC signed a comprehensive partnership agreement with the Tokyo Voluntary Action Center, which plays a central role in promoting volunteerism in Tokyo, in order to foster a volunteer culture, create volunteer legacies and promote the building of an inclusive society by leveraging the strengths of the two organizations.

In Minato Ward of Tokyo where the NEC headquarters building is located, we hold lunch time gardening and family events on holidays to create the "Biodiversity Garden" with the slogan of "Habitat for Parantica sita butterflies in Shiba Park".

In support of "children's cafeterias", one of the programs that Minato Ward has in place to prevent children from eating alone and giving support to parents, NEC joined the Minato Ward Children's Cafeteria Network in February 2020.

In the NEC “TOMONI” Project, the company provides assistance by building on the social contribution programs that it has continued over the years, and employees visit the affected regions to work as volunteers.
